         ***Important Update Information*** 
=============================================================================

- When using a hot swap backplane for either the Intel Server Chassis
SR1400 or SR2400, you MUST update the HSC firmware to the following revisions 
before performing the mBMC firmware update. 

SR1400/SR2400 SCSI HSC 1.06 or later
SR1400/SR2400 SATA HSC 1.08 or later

FAILURE TO FIRST UPDATE THE HOT SWAP CONTROLLER (HSC) ON THE HOT SWAP 
BACKPLANE (HSBP), EITHER SCSI or SATA, MAY RESULT IN A mBMC UPDATE FAILURE OR 
A BOARD FAILURE. ENSURE THAT THE HSC CONTAINS THE REQUIRED FIRMWARE REVISION 
LISTED BEFORE PROCEEDING WITH THE mBMC UPDATE. 

- The mBMC firmware cannot be updated if an Intel Management Module (IMM) is
installed in the system.  To perform the mBMC firmware update, the IMM must 
first be removed from the system.  This issue will be corrected with a future
mBMC firmware update release package.

			SYSTEM HARDWARE REQUIREMENTS/REVISIONS
=============================================================================
Server Board with PC87431M mini-Baseboard Managment Controler (mBMC) from 
National Semiconductor

=============================================================================
		       SYSTEM SOFTWARE REQUIREMENTS/REVISIONS
=============================================================================
- PC87431M mini-Baseboard Managment Controler (mBMC) from National 
  Semiconductor: Firmware Revision 2.40
 
- Latest HSC (SCSI or SATA) backplane firmware.

- Latest FRU/SDR package.

=============================================================================
                         INSTALLATION NOTES
=============================================================================

- The following files are necessary to update the firmware:

  run.bat	- Batch file used to update the mBMC firmware
  m431_240.hex
  mfwu_240.hex	- mBMC 2.40 firmware hex files for the platform
  FWPIAUpd.exe	- DOS utility rev 2.0.1 PR2 which programs the firmware hex
		  file into the flash device.
		  Prior versions of this utility will not work with this FW

Executing the fwpiaupd utility with your own command switches is unsupported 
and may leave your baseboard in a non-operational state! Please use the
provided batch file to update the firmware.

The following command can be used to check for the current version of HSC 
firmware.   "fwpiaupd -i -dirhsc".  Both the Op Code and Boot Block code 
versions will be displayed.  It is the Op Code that is shown above for 
version comparison.    

=============================================================================
                         INSTALLATION PROCEDURE
=============================================================================

- Validate that the server board is a mBMC based system without an Intel(R) 
  Management Module installed. This package does not support mBMC updates
  while the Intel Management Module is installed. Removal of the module is 
  required before proceeding with the mBMC update.
- Validate that the HSC fimrware is either at or higher in the revisions 
  listed above.
- Execute the run.bat file to begin the firmware update process 
- Cycle AC power after the update
- Proceed to install the latest FRU/SDR package.
- Reinstall Intel Management Module if previously installed.
